hey guys i upgraded my 98 to an 02 computer and obviously the fuel guage only reads full...We are using hp tuners and does anyone kno how to do a fuel segment swap on it... Ive read that ppl are using fuel segments from 02 vans but not sure how to do the swap. Is it just changing the numbers or do you have to contact hp tuners..any help is appreciated thanks

i believe you can email somebody at hptuners and they have you send your tune then they do the segment swap and send it back

You have to have both of the files.

Ya we send an email out yesterday...both files? The 02 van and the 98 camaro fuel segments?

sreve

Yes both tune files. You would swap out the system segments.

Van and the car OS must match.

and to be correct we need to swap the van fuel segment onto the 02 camaro pcm?

Correct, unless you know somebody with TunerCat, that will turn on the PWM output for the fuel gauge and set the perameters, that way no segment swap is required and you can around having to use the 2156 OS, since that is the OS that the 2002 van fuel segment works with.

Wrong, Fuel gauge is the system segment along with the a\c which on most trucks
is wired different then an F-Body and becomes your next hoop to go thru.

T\C can turn on the P\W.

Tunercat most certainly change the fuel gauge parameters, also do your own "segment swaps" if needed. The so called "segments" are actually individual calibration files, or modules.

we changed the numbers but couldnt get into the pwm output for the fuel guage using hp tuners...everyone has said you have to send the files in to hp tech and they can do it for you

You can also fix it with efi live if you know someone with it.

Minytrker is correct. EFIlive you can do this function by yourself without the need of anyone.

I believe that tunercat added that functionality just recently as well.

A couple of years for Tunercat.
